How to use JMeter with ajax request?
I have a button with is clicked and by using fiddler I can find the session id which is being sent to the server.
What should I do next using the JMeter in order to handle this.
EDIT:
Let's say I have in my hand the header which call the request. The JSESSIONID AJAXREQUEST
and so on where should I put it ?...
I putted it in http header manager name and value.
Jmeter will not execute Javascript embedded in your web page. However AJAX request is also a HTTP request that Jmeter will be able to run as a separate HTTP request and upon getting the response you can have post processors (using XPATH or REGEX) to extract the session id in a Jmeter variable.
Alternatively you can record the Jmeter scripts using Jmeter proxy and then all the HTTP requests will be recorded for you and you will just need to attach a post processor manually.

I'm trying to record a script in JMeter. I'm getting a 401 error in the login request. I see that the login request is sending a token to the server and I have to correlate this token however I'm not able to find any token in the response body or response header of any previous request. What should I do?
There are 4 sources where the "token" could come from:
Response body
Response headers (including cookies)
URL (as a result of a redirection), if this is the case you might need to play with Redirect Automatically and Follow Redirects checkboxes in the HTTP Request sampler (or HTTP Request Defaults)
The token can be generated by JavaScript. As per JMeter project main page:
JMeter is not a browser, it works at protocol level. As far as web-services and remote services are concerned, JMeter looks like a browser (or rather, multiple browsers); however JMeter does not perform all the actions supported by browsers. In particular, JMeter does not execute the Javascript found in HTML pages. Nor does it render the HTML pages as a browser does (it's possible to view the response as HTML etc., but the timings are not included in any samples, and only one sample in one thread is ever displayed at a time).
so if this is the case - you will have to replicate the logic of the associated JavaScript function(s) using JSR223 PreProcessor
I have a login form that has form method set to POST, form-action set to a servlet, and an OnSubmit function to check the field data.I want to performance test a file download funcitonality that lies behind this login form. To acheive this i am running a parallel sampler to login and then download the file.
The first sampler is for the login and the second one is to dowload the file.
In the first sampler, I want to POST data on this form using JMeter's HTTP Reqest Sampler.
I have inspected the form and created a sampler with three parameters, the username, the password and one more non-discloseable field. I have set the path to the servlet since it is the one handling the requests for the form.
The post request doesn't do anything in this case.
What should i do or check or modify to make sure that the POST request is hitting the correct endpoint and that it actually submits the form data.
You need the samplers to be sequential, I think if you attempt to download the file without prior logging in - the request will fail somewhere somehow.
If it is not sufficient and you would like to add an extra level of checks, i.e. test that the endpoint returns anticipated response code or has certain text you could add Response Assertion as a child of the request and add pass/fail criteria there.
If you don't know how to properly build login and download requests, the easiest way is just recording them using HTTP(S) Test Script Recorder, JMeter will capture the requests and generate relevant HTTP Request samplers and HTTP Header Managers
We are using the jmeter recording template to see the api requests by our unsigned app.
When we use charles as the proxy, we are getting all the urls properly.
But when we use the jmeter recording template, we get 'MISSING PARAMETERS' for all GET requests. Essentially, jmeter does not get any parameters that are sent with the GET request.
POST requests work properly.
Any advice?
For convenience JMeter stores the request parameters under "Parameters" section of the HTTP Request sampler
it's better to work with attribute-value pairs for parameterization or correlation purposes than having to edit the URL string which might be very long.
If you replay your recorded request(s) and look into Request tab of the View Results Tree listener you will see that the parameters are concatenated to protocol, domain, etc. in the URL:
I want to execute Ajax requests in JMeter. I record my test plan with JMeter and BlazeMeter but none can handle Ajax requests. How can I solve my problem?
Or is there any tool that can send concurrent Ajax requests?
Thanks in advance,

By default, Ajax requests can't be simulated by JMeter as it does not process .js files (As of 3.1 version). You have to explicitly add the requests (HTTP Samplers) for AJAX requests.
Use Network tab of a browser (F12 option) and filter the traffic by xhr, which shows only AJAX requests. Add those requests as HTTP Samplers in the script at the point you needed in the Test Plan.
Browser can process .js files, hence AJAX requests are sent from the browser. When you record the script using HTTP Test Script Recorder, as you are using the browser to navigate, even AJAX requests (originated from js files) will also be added/recorded to the Test Plan.
Since JMeter can't process .js files due to limitation, manually add the AJAX requests (nothing but HTTP Get or Post requests) using HTTP Sampler, if you are building the Test Plan without HTTP Test Script Recorder.
Note: If you are using HTTP Test Script Recorder, no need to add them manually as they are already recorded in the Test Plan.
you can do that by recording http traffic with JMeter Proxy
http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf
but it is only possible to replay the same traffic, can be problematic for sessions, cookies...
Better solution is to use WebDriver
https://jmeter-plugins.org/wiki/WebDriverTutorial/
https://jmeter-plugins.org/wiki/PluginInstall/
the needed package is https://jmeter-plugins.org/files/packages/jpgc-webdriver-1.4.0.zip
It is not possible as kicking off more threads than originally defined in the Thread Group is not currently supported, the feature is being tracked as Bug 53159. AJAX requests are "normal" HTTP Requests so JMeter can record and replay them, but when it comes to asynchronous execution - you cannot do this as of now. The workaround options are in:
Use WebDriver Sampler plugin so each JMeter virtual user will kick off a real browser. Warning: this way is very resource intensive.
Use scripting, i.e. JSR223 PostProcessor to kick off AJAX-driven requests via Apache HttpComponents
Develop your custom sampler. You can use the current way of handling embedded resources as a reference.

I had this same problem after recording samplers using the JMeter Proxy. The answer was on this blog post: https://lincolnloop.com/blog/load-testing-jmeter-part-1-getting-started/ - see the Ajax Requests section.
Add an HTTP Header Manager for the ajax request and make sure you are sending the X-Requested-With:XMLHttpRequest header.
I have an application for load testing. I am using JMeter for this purpose. I have added CSV Data Set Config to the While Controller where former reads URL from a csv file. Also, I have added a HTTP request sampler inside the controller.
Now, I have both get and post requests . In addition to that, I have to send file data with few http post requests. Is there a way so that jmeter can decide http request type automatically and create a request accordingly?
Should I create separate While Controller for both GET and POST requests?
You could add method field (post,get) and use an
IfController to eithet call a post or get depending on method value.
